GEORGE HARR SON SHEFFIELD AND JAMES DENIS JTWINBERRO'W, OF. NEWcAs'rLE-UPoN-TYNE, ENGLAND.

DOOR AND APPARATUS THEREFOR FOR USE UPON HbPPER-WAGONS.

SPECIFICATION forming'pa'rtof Letters Patent No. 7q.s,221 dated December 29, 190s.

'Application' filed September 5, 1903. Serial No. 172,170. (No model.)

Beitknown that we, GEORGE HARRISON SHEFFIELD and JAMES DENIs TWINBERROW,

subjects of the King of Great Britain and Patent in Great Britain,

Ireland, residing at New Bridge street, Newcastle-.upon-Tyne, England, have invented certain new and useful Improvements in Connection with ,Doors and the Apparatus Therefor for Use upon Hopper-Wagons, (for which we have made application for Letters No. 19,446, hearing date September 4, 1902; in India, No. 522 /02, hearing date December 29, 1902, andin Germany, application filed May 23,1903) of which the following isa specification.

This invention relatesto methods of operating and the apparatus employed upon doors for use upon hopper-wagons for railways and the like, more especially in cases wherein the doors are operated'by winding-gear, the

controlled gearing, so arranged that the doors-usually two innu rnber -may be either simultaneously or independently operated, such gearing being alsoarranged for manipulation from either side ofthe wagon.

The invention consists in arranging the gearing for the winding-drums in such manner that the latter may be simultaneously rotated or on' the manipulation of a suitable clutch or clutches drums may be rendered inoperative, so that operation of the gearing simply drives one at twice'its usual speed if the other is jam me'd.

The invention still further consists in special arra ements and constructions of gearing and details connected therewith for 'ef-' fectively operating the doors hereinafter fully described.

Several modesof carrying out the invention lit ing.

Fig. 1 isa view similarto Fig. 1 of the right-hand half of the same wagon. Fig. 2 is an elevation,on a larger scale,of one door and the gear- Fig. 3 is'a half-plan of the gearing cor- Fig. 4. is a transverse responding to Fig. 2.

Figs. 10 and 11 are side and sectional elevations of a modified form of drum, Fig. 12 being a diagrammatic plan illustrating the application of this type of and 14. show, respectively, in elevation and plan a form of ropegrip used when the modified form of drum is employed. Figs. 15 and 16 are a sectional e'levation and plan, respectively, of .a modified form'of gearing, and Figs, 17 and 18 are similar views of another modified form of. gear-v diagrammatic plan illusdiiferential gear. In carrying out the invention according to one modification in the application to a doublehopper wagon, as illustrated in Fig. 1, the hop persa b are fitted with doors 0 (1,3d3-Pt9di0 slide longitudinallytoward or away from the center of the wagon. The doors are fitted with rollers e, resting on guide-rails f, carried in any suitable manner from the sides of the hoppers or from the vehicle-body. The rolling.- Fig. 19 is a ers e are preferablycarried in suitablebearings on channel-irons g,forming the side girders or sills of the doors. The doors a d are operated by pairs of wire 'ropes or chain cables h 11,-res'pe'ctiVely, there being two pairs of ropes to each door,one rope on each side. The ropes are attached. to the doors by clipping devices,.such as shown in detail in Fig. 6. bolted to thedoors, having These consist of brackets 70,

V-guides t alter- 45 1ength being passed through an. opening 11 provided for that purpose. tightened up,'whereupon the rope is firmly natinglwith screwed eyelets m on their upper faces. The ropes are'led alternately overthe'V- guides and through the eyelets and firmly secured bytightening up the nuts n on theeyelet-bolts. As explained hereinafter, the door .0 is secured to the upperpar'ts of the ropes h and the door d to. the lower parts of theropes 'i. 'For t hi s reason 'the brackets 70 on the door are much longer than the brackets It on the door d, the clip-'- ping device shown in Fig. .6 being intended to-grip the upper part of the rope.

The ropes ht are led around fixed but ad justable guide-pulleysp p and onto winding drums r s, respectively. The pulleys pare carried in bearings-2f, supported ;by adjustable bolts w in fixed brackets w, forming stops limiting'the travel of the doors, the bearings being preferablyformed in one or connected by'oross-bars a. By adjusting the bolts w the tension of the ropes may tie-regulated as desired. The winding-drums a" s are carried on shafts 2 2, extending transversely .across the wagon, preferably at the'center .thereof, as shown in Figs. 1 to V The'co-nstruction of the drums according to one form will beunderstood on reference to Figs. 8 and 9, wherein one dr um is illustrated, the other drums being identical therewith. 'A disk 3., a drum 4, and a second disk 5 are mounted on the end of the shaft 2, which is provided with ashoulder 6 to resist lateral movement of the disk 3 and is fitted .with a feather or key 7 and a not 8 and yvashe'r on the outer screwed end. The edges of the rim of the drum '4are beveled; and project into re- .cesses 9 10, formed'in thedisks 3 and 5. The

rope 'to'besecured to the'drum is first passed round onc'e,- so as to lie on the beveled-edge opposite, say, the disk.3, once or twice round the drum 4, oif to the door, and round the guide-pulley, back again to the drum, being wound once ortwice about the drum 4, and finally round. the beveledfedge'opposite the other disk 5, the-free end and any excess The nut 8 is then secured between the beveled edges of'the drum 4 and the-disks 3 and 5.=

or words toindicate .in'which direction they should be rotated. in order, to open or closev the doors.

The drums 1' s are rotated to-open or close .the doors by means of a hand-wheel 12 on a driving-shaft 13, Figs. 2 and 3, a pinion 14,

on which gears into a wheel-'15 on a central shaft 16, a second pinion; 17 onwhich ears intoa second 'wheel 18 011" the shaft-2o the.

such as shown at'19, Fig. 3. These'elutches are independently manipulated by lovers 2 21, one on each sideof the wagon, but each lever is connected to a free companion lever.

on the opposite side .bya connecting-link 22 in order that either of the clutches maybe manipulated from either side of the wagon.

It willthus be. understood that the doors may be independently openedor shut in any desired order, or both'may be opened or shut -nal comprises a knuckle-joint 23,-bol'ted to a bracket 24:,in. turn-bolted to the door.

The drum is-of split formation, the"meet'- ingedges of the halves 25 being beveled or formed, as shown in Fig. 10, and helicallyarranged, as indicated. at'Figs. 10 and 12.

A rope is secured at one'end to one terminalon the door, passed over a, guide-pulley,

next passed once or twice round one-half of the drum, then passed around and gripped in the helical groove, being securedv therein by a'tightening-nut 2.6. Leaving the grooveat the point 27,,Fig'. 12,-it is again'pa'ssedonce or twice over .the'drum ,-but on the opposite half, and its free end is finally secured bya second terminal on the door. "In a' modified arrangement worm-gearing is substituted for spur-gearing, as-shown in. Figs-15 and 16. Fig. 15 is an irregular sec-, tion, the left-hand half, being a section throughthe 'worm' on the far-side of the" wagon .and the other half, asection through that on the near side.- Fig. 16 shows the gear-' ing on' the near'side, the worm-being omitted for clearness. The 'hand-wheell2 is sea cured to the shaft 13. A bevel-pinion 28 is loose on the shaft, but is. adapted-when required to be securedto [it by a clutch- 19,-s0

'as';.to 'gear'with' andv drivea pinion29 on a worm-shaft 30,,the worm ofwhich 'drives a worm-wheel 31 .on the shaft 2 of the drum 8.

It willthus beseen-thatwhen the wheel 12 operates the drums as the right-hand door is operated. In order to enable the left-hand drum and .door to be operated,.a clutch'1'9- and similar gearing .28 to "31 is provided on trolledfrom either side of the wagon, a 'set of duplicate clutch-levers 21 are provided similar to those already described with reference to Figs. 3, 5, and 5*.

A further modified and simplerforrn of. to winch-gearing isillustrated in Figs. 17 and 18.* Fig. ISshows the gearing on the near side. The drums r 8, preferably of the construction hereinbefore described,are mounted on shafts 2 V 2. These shafts are independ- 15 ently operated from shafts 13 13 through piuions 14 14, gearing directly with wheels 18 18 on said shafts 2 2. The shafts 13 extend across the wagon, and each carries a hand-wheel or a star-wheel 12 on each end. 2c. The star-wheels may be operated by lengths ,of tubing or other levers in the well-known manner.- The arms of the'star-wheels project radially and are ou-twardlyinclined, so that though they lie wholly within the vertical plane defining the maximum width of the wagon the lever when in place projectsbeyond such plane describing a conical path 'when the shaft is rotated,the said path bein}; clear of the sill of the wagon andof the adjacent star-wheel. A The above-described gearing is preferably employed with doors fitted with clips and arranged, as herei'nbefore describedwith reference to Figs. 1 to 6.

differential gear may be employed, so that as one door is locked or jammed the other door.

opened at an increased speed. .In this form i of gearing a single driving-shaft l3 is pro-- vided with a hand-lever 12 on each end. Loose on the shaft are two pinions'l i 14, gearing with wheels 18 18,-keyed on the drumshaftsfl22. Secured to or'i'n one with each ential gear-4n the form shown a bevel-wheel 32-.--the other elements-viz planet-pinions 33-being carried on arms fixed-to the shaft [13. Any other form of equivalent differen- 'tial gear maybe adopted.

It is preferred to use the -above-des'cribed gear with drums, doors, and fittings such as l j hereinbefore described. I i

, The hereinbefore-described methods'of opcrating doors longitudinally of the wagon are equally applicable to the transverse opera+ tion of doors, to place the drum-shaft at one side of the ently' or simultaneously operated, substan- In a still further-modified form of gearing, such as shown diagrammatically in Fig. 19, a

-50 pinion is one element of an ordinary differ it then being found preferable wagon and guide-pulleys at the-other side, the drum' shaftbeingdriv'eu by a transverse.

worm-shaft fitted with suitable time wheels oralevers.

In any of the hereinbefore-described gears, for operating'the doors the drums may be replaced bysuitably-sprocketed wheels on;- gaging with chains infplace of flexible wire ropes.

Having nowdescribed' our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1i In railway andlike double-hopper wagons wherein the doors are operated by flexible winding-gear, twosets of winding-gear, one for each door, adapted to be either independently or simultaneously operated from the samedriving-shaft,= substantially as herein before described.
